Objectives: Social support is an important resource that has been associated with better mental and physical health outcomes among HIV-positive people. However, researchers have not adequately explored how social support functions among HIV-positive African Americans. The purpose of the current study was to understand whether HIV-related support resources are associated with relational functioning and HIV-related problems among a sample of HIV-infected African American dyads.
Method: Exactly 34 HIV-infected (i.e., seroconcordant) dyads compromised of HIV-positive African American adults and their HIV-positive adult "informal supporters" from 3 Midwestern urban cities completed psychosocial questionnaires and a communication task. Using the actor-partner interdependence model, we analyzed dyadic data to determine whether there were actor and/or partner effects within dyadic relationships on measures of conflict and HIV-related problems, communication about these problems, and health symptoms.
Results: We found significant negative relationships between perceived support and HIV-related problems and perceptions of problem inequity within dyads and a positive relationship between perceived support and communication about these problems within dyads. Contrary to our expectations, we found no relationship between social support and HIV symptoms, relational conflict, or perceptions about dyadic partners' HIV-related problems.
Conclusions: Although our study precludes drawing causal conclusions, we found evidence of a relationship between the personal experience of HIV-related problems, communication about these problems, and perceptions of social support among a small sample of HIV-infected African American dyads. These findings suggest the need to consider how support-related communication within HIV-infected dyads might influence and be influenced by problem perceptions.

Background: Attention-deficit/hyperactivity disorder (ADHD) is a common neuro-developmental disorder that often persists into adulthood. Moreover, it is frequently accompanied by bipolar disorder (BD) as well as borderline personality disorder (BPD). It is unclear whether these disorders share underlying pathomechanisms, given that all three are characterized by alterations in affective states, either long or short-term.

Objectives: Racial and ethnic differences in long-term outcomes associated with medications for opioid use disorder (MOUD) are poorly understood.
Methods: The present analyses were based on 751 participants with opioid use disorder (OUD) who were initially recruited from opioid treatment programs located in California, Connecticut, Oregon, Pennsylvania, and Washington and participated in a randomized controlled trial and at least one follow-up interview. 9.

Prostate cancer, a common malignancy in older men, often requires laparoscopic radical prostatectomy, considered the gold standard treatment. However, postoperative complications can significantly impact quality of life and psychological well-being. The emergence of mobile internet health management offers a promising approach for accessible and effective post-discharge care.

The urban agglomeration represents the predominant form of new urbanisation, yet the evolution of its internal spatial structure exhibits pronounced spatial and temporal heterogeneity. This study concentrates on the Bohai Rim urban agglomeration, one of three major urban agglomerations in China, which has received comparatively limited research attention but has also undergone substantial urbanisation. Therefore, we reassessed and explored the spatial-temporal evolution of the spatial structure of urban expansion using Exploratory Spatiotemporal Data Analysis (ESTDA), and summarized the driving mechanisms using Geographically and Temporally Weighted Regression (GTWR).

Consensus algorithms play a critical role in maintaining the consistency of blockchain data, directly affecting the system's security and stability, and are used to determine the binary consensus of whether proposals are correct. With the development of blockchain-related technologies, social choice issues such as Bitcoin scaling and main chain forks, as well as the proliferation of decentralized autonomous organization (DAO) applications based on blockchain technology, require consensus algorithms to reach consensus on a specific proposal among multiple proposals based on node preferences, thereby addressing the multi-value consensus problem. However, existing consensus algorithms, including Practical Byzantine Fault Tolerance (PBFT), do not support nodes expressing preferences.
